This tour is not ready yet, but you can click through and look at the pictures if you wish! Please come back in 30 days.

This page is the start of the tour of the Evolution of the Solar System. The navigation button for the tour can be found at the top of the page. The evolution of the solar system is a big topic! There are a lot of things to discuss, not only the forming of the Sun but of the 9 planets and various interesting moons. Because there is so much to talk about, the tour has been broken into three segments. This is the first segment. In this segment we will present the solar nebula and the forming of the Sun and planets. You can skip ahead if you like by using the links at the bottom of this page. To proceed with the tour, just press the forward link (F) on the button at the top of the page.
